An infrared shielding sheet includes a laminated film formed by alternately laminating a high refractive index resin layer containing fine particles and a low refractive index resin layer containing fine particles. At least one of the low refractive index resin layers has a value of 0.1 or more that is obtained by subtracting a refractive index at an arbitrary wavelength from 780 to 2500 nm from a refractive index at a wavelength of 550 nm. The low refractive index resin layer has a refractive index lower than a refractive index of the high refractive index resin layer at any wavelength in a range from 550 nm to the arbitrary wavelength inclusive.

Problem To provide a process for producing single-walled carbon nanotubes with which highly pure, high-quality single-walled carbon nanotubes can be produced with high efficiency, and to provide a transparent conductive film using the single-walled carbon nanotubes obtained by that production method. Solution A process for producing single-walled carbon nanotubes by chemical vapor deposition (CVD), wherein particles of a nonmetallic material containing 500 ppm or lower of metallic impurities including metals and compounds thereof are used as growth nuclei; and after a growth gas is introduced into a furnace used for growing carbon nanotubes, the growth gas used in an initial stage of growth of carbon nanotubes and the growth gas used in a stage of growth of regular carbon nanotubes (stationary growth stage) thereafter are prepared to different compositions and different partial pressures.

[Problem] The present invention relates to: a heat ray shielding adhesive which is used in bonding to a windowpane and the like and shields heat rays; a heat ray shielding transparent adhesive sheet; and a method for producing the heat ray shielding adhesive. The present invention provides a heat ray shielding transparent adhesive sheet which has high transmittance in the visible light region, low haze and more excellent transparency. [Solution] Transparency and heat ray shielding properties can be imparted in a simpler manner by using a heat ray shielding adhesive composition which contains fine heat ray shielding particles that have a half-value width of the first main peak of from 0.01&#xb0; to 0.80&#xb0; (inclusive) as determined by X-ray diffraction pattern, and a heat ray shielding transparent adhesive sheet is therefore able to be produced at low cost.
